廢白土是指在動植物油精煉和礦物油精煉的過程中使用過的活性白土，簡稱(cheng)廢(fei)白土(tu)。我(wo)國食用油生產企業(ye)和(he)石化(hua)煉油企業(ye)數量較(jiao)多，規模也較(jiao)大(da)，每年產生的廢(fei)白土(tu)數量非常巨(ju)大(da)。以前廢(fei)白土(tu)的處(chu)理(li)(li)方(fang)式多為(wei)填(tian)埋(mai)或焚燒，這(zhe)種(zhong)處(chu)理(li)(li)方(fang)式會對環境產生一定(ding)的影響。隨著國家對環境保護的重視和(he)管理(li)(li)，這(zhe)種(zhong)對環境有害的處(chu)理(li)(li)方(fang)式已經被禁止使用了。
現在廢(fei)白(bai)土(tu)(tu)的(de)(de)無害化(hua)處理成了很多活性(xing)白(bai)土(tu)(tu)使用(yong)(yong)(yong)單位非常關心(xin)的(de)(de)事。而國內的(de)(de)某些(xie)科研機(ji)(ji)構在廢(fei)白(bai)土(tu)(tu)的(de)(de)回收利用(yong)(yong)(yong)領域已經取得(de)良好的(de)(de)科研成果(guo)，有(you)的(de)(de)機(ji)(ji)構基本可以(yi)實現廢(fei)白(bai)土(tu)(tu)的(de)(de)高值(zhi)無害化(hua)利用(yong)(yong)(yong)。如徐州工(gong)(gong)業職(zhi)業技術學院(yuan)副教授徐云(yun)慧研發(fa)的(de)(de)廢(fei)白(bai)土(tu)(tu)在橡膠中(zhong)的(de)(de)應(ying)用(yong)(yong)(yong)、上海交通(tong)大學研發(fa)的(de)(de)廢(fei)白(bai)土(tu)(tu)在瀝青中(zhong)的(de)(de)應(ying)用(yong)(yong)(yong)、中(zhong)國石油(you)化(hua)工(gong)(gong)股份(fen)有(you)限公司(si)濟南分公司(si)與山東(dong)科技大學合(he)作研發(fa)的(de)(de)廢(fei)白(bai)土(tu)(tu)在鑄造(zao)翻砂中(zhong)的(de)(de)應(ying)用(yong)(yong)(yong)、燕山石化(hua)公司(si)通(tong)過熱蒸汽噴射技術回收廢(fei)白(bai)土(tu)(tu)中(zhong)的(de)(de)潤滑油(you)等回收利用(yong)(yong)(yong)項目。
